ICE-TOOL.

Specification of Letters Patent.

Patented July 12, 1910.

Applid ation filed April 1, 1910. Serial No. 552,813.

To all whom it may concern:

Be it known that I, PETER RonAnon, a citizen of the United States,residing at WVillink, in the county of Erie and State of New York, haveinvented a new .and useful Ice-Tool, of which the following is aspecification.

This invention has relation to devices for removing frozen snow and icefrom side walls, and has for its object to provide a simple andefficient device of this kind, and also one which can be employed forcutting grooves in the ice or frozen snow to make a path having a roughsurface.

Vith these objects in view, the invention consists in a novelconstruction and arrangement of parts as will be hereinafter describedand claimed.

The invention is illustrated in the accompanying drawing, in which,

Figure 1 is a perspective View of the same. Fig. 2 is a front elevation.Fig. 3 is a section on the line 3? of Fig. 1.

In the drawing, 5 denotes the blade of the device and 6 is a handle towhich the blade is fastened in any suitable manner. The blade comprisesupper and lower sections 7 and 8, respectively, extending at an angle toeach other. The upper portion extends in line with the handle, and thelower portion is arranged at an oblique angle thereto. At the junctionof the upper and lower portion of the blade is a series of openings 9arranged in a row extending transversely of the blade. The extremity ofthe lower portion of the blade is brought to a sharp edge 10. Formedintegral with the upper portion of the blade, are teeth 11 which arebent rearwardly through the openings 9, so as to project from the backof the blade in line with the upper portion 7 thereof. The extremitiesof the teeth are formed into two sharp points 12 as shown in Fig. 2.

The teeth 11 are corrugated in the direction of their length, whichstrengthens them and also forms teeth having a tendency to cut or sheardownwardly into the ice. The back of the teeth are beveled to form thesharp points, and they may therefore be sharpened from beneath, and arealso selfsharpening. The portions of the blade between the openings 9,and at the ends of the blade, are corrugated as indicated at 13 to givestrength to the blade when it is used as a spud. Each tooth has a singlecorrugation, said corrugation or ridge being on the underside, so thatwhen the tooth is sharpened, the double point is retained. The teeth areself-sharpening when scraped on a stone or cement walk.

In use, when it is desired to make a rough path on the ice or frozensnow, the blade is placed in a position so that the points of the teeth11 come in contact with the surface of the ice or snow, as shown in Fig.3. The blade is then run over the frozen surface, whereupon grooves arecut in the same by the teeth, and a path may thus be made having a roughsurface.

The device herein described is simple in construction, and can be easilyoperated as stated, and it therefore effectually serves the purpose forwhich it is desired.

lVhat is claimed is:

l. A device of the class described comprising a blade having upper andlower portions extending at an angle to each other, the back of theblade, at the junction of said portions having a plurality of projectingteeth extending in alinement with the upper portion of the blade.

2. A device of the class described comprising a blade having upper andlower portions extending at an angle to each other, and having a row ofopenings at the junction of said upper and lower portions, and teeth onthe upper portion of the blade projecting through the openings to extendfrom the back of the blade.

3. A device of the class described comprising a blade having twoportions extending at an angle to each other, and the back of the blade,at the junction of said portions having a plurality of projecting teeth.

In testimony that I claim the foregoing as my own, I have hereto ailixedmy signature in the presence of two witnesses.

PETER ROBARGE.
